This map, drawn up by the Mexican cartographer Antonio García Cubas, was originally published as part of the Geographical and Statistical Atlas of the United Mexican States in 1858. It is the first atlas of Mexico produced by a Mexican cartographer. This particular edition was published by Debray Sucesores in 1886.

The map depicts the state of Sonora in northwestern Mexico, with its most populated localities, major geographic features and administrative boundaries (in different colours). The state was bordered by the United States to the north, Chihuahua to the east, Sinaloa to the southeast, the Gulf of California to the west, and Baja California to the northwest.

The lower left-hand side also incorporates two detail boxes: one dedicated to the Puerto de la Libertad and the other to the bay of Guaymas, the two most important ports in Sonora in the second half of the 19th century.
